Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to FIG. 1, a flow 100 of one embodiment of a method for processing information in accordance with the present disclosure is shown. The method for processing information comprises the following steps:
and S101, receiving the audio collected by the vehicle-mounted audio collecting equipment in response to the fact that the preset audio collecting interface is called by the vehicle-mounted terminal application.
In this embodiment, the in-vehicle terminal may include a preset audio capture interface. The audio acquisition interface can record audio acquired by an in-vehicle audio acquisition device (such as a microphone or a microphone array). In practice, the preset audio capture interfaces corresponding to different operating systems may not be the same. Taking an operating system of the vehicle-mounted terminal as an android system as an example, the preset audio acquisition interface may be an AudioRecord. The vehicle-mounted terminal application installed on the vehicle-mounted terminal can call the preset audio acquisition interface to acquire audio. An execution subject of the method for processing information, for example, a processor of a vehicle terminal, may determine whether a preset audio capture interface is called by a vehicle terminal application in various ways, and if it is determined that the preset audio capture interface is called by the vehicle terminal application, the execution subject may receive audio captured by a vehicle audio capture device (for example, a microphone or a microphone array). In practice, the in-vehicle audio collecting device may collect voice information of a driver or a passenger in the vehicle, noise in the vehicle, acoustic echo caused by a speaker in the vehicle, and the like.
And S102, processing the audio collected by the vehicle-mounted audio collecting equipment to obtain the processed audio.
In this embodiment, the execution subject may perform various processing, for example, noise reduction processing, on the audio acquired by the in-vehicle audio acquisition device, so as to obtain processed audio. In practice, one or more processing methods for improving the quality of the audio collected by the vehicle-mounted audio collecting device can be set according to actual needs to process the audio collected by the vehicle-mounted audio collecting device so as to obtain high-quality processed audio.
S103, the processed audio is sent to the vehicle-mounted terminal application calling the audio acquisition interface so that the vehicle-mounted terminal application can perform preset processing based on the processed audio.
In this embodiment, the execution main body may send the processed audio obtained in S102 to the vehicle-mounted terminal application calling the audio collection interface, so that the vehicle-mounted terminal application performs preset processing based on the processed audio. Here, the in-vehicle terminal application calling the above-described audio collection interface may be a voice-related application, for example, an instant messenger, a bluetooth car phone, an input method application, or the like. Therefore, after the vehicle-mounted terminal application receives the processed audio, the processed audio can be correspondingly processed according to the processing logic of the vehicle-mounted terminal application.
In some optional implementations of this embodiment, the in-vehicle terminal application that invokes the audio capture interface may include a media player. And S103 may be specifically performed as follows;
and sending the processed audio to a media player for the media player to execute preset operation.
In this implementation, the execution main body may transmit the processed audio obtained in S102 to the media player. The media player, upon receiving the processed audio, may perform the following operational steps 1) and 2):
1) and performing voice recognition on the processed audio to obtain a voice recognition result.
In this implementation, the media player may perform speech recognition on the received processed audio, thereby obtaining a speech recognition result. Here, the voice recognition result may be text information.
2) And acquiring the information to be played from a preset information set based on the voice recognition result, and playing the information to be played.
In this implementation manner, according to the voice recognition result, the media player may obtain the information to be played from the preset information set, and play the information to be played. Here, the information to be played may include, but is not limited to, audio information, video information, and the like. In practice, an information set can be preset for the media player, and the information set can be stored locally in the vehicle-mounted terminal or in the cloud. The information set may include, but is not limited to, audio information, video information, and the like. In this way, the media player can determine information from the corresponding information set as information to be played according to the voice recognition result. For example, for each piece of information in the information set, a tag may be set according to the content included in the information. Taking video as an example, the tags may include, but are not limited to, names of videos, names of characters in videos, directors of videos, events described by videos, and the like. The media player may extract one or more keywords from the speech recognition result in various ways and match the extracted one or more keywords with the tags of each piece of information in the information set. And determining information from the information set as the information to be played according to the matching result. Through the implementation mode, the media player installed on the vehicle-mounted terminal can determine the information to be played based on the processed audio, so that the determined information to be played is more accurate.
In some optional implementations of the embodiment, the audio collection interface is configured to be invoked by at least one in-vehicle terminal application.
In this implementation manner, the preset audio acquisition interface may be invoked by at least one vehicle-mounted terminal application installed on the vehicle-mounted terminal. For example, the vehicle-mounted terminal applications installed in the vehicle-mounted terminal and having the audio acquisition requirement can all acquire audio by calling the audio acquisition interface. Because the audio acquired by the vehicle-mounted terminal application by calling the preset audio acquisition interface is the processed audio, the vehicle-mounted terminal application can acquire the high-quality processed audio, and subsequent processing of the vehicle-mounted terminal application is facilitated.
With continued reference to fig. 2, fig. 2 is a schematic diagram of an application scenario of the method for processing information according to the present embodiment. In the application scenario of fig. 2, in response to determining that the preset audio capture interface is called by the in-vehicle terminal application, the processor of the in-vehicle terminal may receive audio 201 captured by the microphone. Then, the processor of the in-vehicle terminal may process the audio 201 collected by the microphone to obtain a processed audio 202. Finally, the processor of the vehicle terminal may send the processed audio to the vehicle terminal application 203 calling the audio collection interface, so that the vehicle terminal application performs preset processing based on the processed audio.
According to the method provided by the embodiment of the disclosure, before the audio collected by the vehicle-mounted audio collecting device is sent to the vehicle-mounted terminal application, the audio collected by the vehicle-mounted audio collecting device is processed to obtain high-quality processed audio, so that the audio quality obtained by the vehicle-mounted terminal application is better, and the subsequent processing of the vehicle-mounted terminal application is facilitated.
With further reference to FIG. 3, a flow 300 of yet another embodiment of a method for processing information is shown. The flow 300 of the method for processing information includes the steps of:
s301, responding to the fact that the preset audio acquisition interface is called by the vehicle-mounted terminal application, and receiving the audio acquired by the vehicle-mounted audio acquisition equipment.
In this embodiment, S301 is similar to S101 of the embodiment shown in fig. 1, and is not described here again.
S302, determining the audio played by the vehicle-mounted loudspeaker as reference audio.
In this embodiment, the execution subject may determine the audio played by the in-vehicle speaker as the reference audio. Generally, audio to be played in the in-vehicle terminal may be played through the in-vehicle speaker after being processed through the audio power amplifier. At this time, the audio played by the in-vehicle speaker may be determined as the reference audio. For example, the audio power amplifier processed audio may be used as the reference audio.
And S303, according to the reference audio, performing echo cancellation processing on the audio collected by the vehicle-mounted audio collecting equipment.
In this embodiment, the execution subject may perform echo cancellation on the audio collected by the in-vehicle audio collection device according to the reference audio determined in S302. As an example, an AEC (Acoustic Echo canceller) may be employed for the Echo cancellation processing. AEC is based on the correlation between the loudspeaker signal and the multipath echo generated by it, establishes the speech model of the far-end signal, estimates the echo by using the speech model of the far-end signal, and continuously modifies the coefficient of the filter, so that the estimated value is closer to the real echo. Then, the echo estimation value is subtracted from the audio collected by the vehicle-mounted audio collecting device, so that the purpose of eliminating the echo is achieved, and the AEC also compares the audio collected by the vehicle-mounted audio collecting device with the past value of the loudspeaker, so that the acoustic echo of multiple reflections with prolonged delay is eliminated.
S304, noise reduction processing is carried out on the audio frequency after echo cancellation processing based on a preset noise reduction algorithm, and the processed audio frequency is obtained.
In this embodiment, the execution subject may perform noise reduction processing on the audio after the echo cancellation processing based on a preset noise reduction algorithm, so as to obtain the processed audio. As an example, a preset noise reduction algorithm may be integrated in the audio codec to implement the noise reduction process. In practice, when the vehicle-mounted audio collecting device collects audio in a vehicle, noise in the vehicle, such as airflow noise when the vehicle is running, engine noise, and the like, is collected. Therefore, noise reduction processing is required for audio. Here, the noise reduction algorithm may be various algorithms capable of performing noise reduction processing on audio.
In some optional implementations of the present embodiment, the preset noise reduction algorithm may be determined by:
firstly, acquiring noise audio collected by a vehicle for test in the driving process.
In this implementation, the algorithm determination execution subject for determining the noise reduction algorithm may be the same as or different from the execution subject for processing the information. The algorithm determines that the executing body can acquire the noise audio collected by the vehicle for testing during the driving process. Here, the test vehicle may refer to a vehicle that collects noise audio through real-vehicle drive test. In practice, the vehicle for testing can be controlled to run under preset conditions (for example, preset vehicle speed, preset road conditions and the like), and noise audio in the vehicle can be collected during running.
And then, carrying out noise reduction processing on the noise audio by using at least one candidate noise reduction algorithm to obtain a noise reduction processing result.
In this implementation manner, the algorithm determination executing body may perform noise reduction processing on the noise audio respectively by using at least one candidate noise reduction algorithm, so as to obtain noise reduction processing results corresponding to various candidate noise reduction algorithms.
And finally, determining the candidate noise reduction algorithm from the at least one candidate noise reduction algorithm as a preset noise reduction algorithm based on the noise reduction processing result of the at least one candidate noise reduction algorithm.
In this implementation manner, the algorithm determination executing entity may determine, according to the denoising processing result of at least one candidate denoising algorithm, one candidate denoising algorithm from the at least one candidate denoising algorithm as a preset denoising algorithm. As an example, the algorithm determination executing body may select a candidate noise reduction algorithm corresponding to a noise reduction result with the best noise reduction effect from the noise reduction results as a preset noise reduction algorithm. Through the implementation mode, one candidate noise reduction algorithm can be selected from multiple candidate noise reduction algorithms to serve as the preset noise reduction algorithm based on the noise audio collected by the vehicle for testing in the driving process, so that the preset noise reduction algorithm is more suitable for the driving noise environment of the vehicle.
S305, the processed audio is sent to the vehicle-mounted terminal application calling the audio acquisition interface, so that the vehicle-mounted terminal application can perform preset processing based on the processed audio.
In this embodiment, S305 is similar to S103 of the embodiment shown in fig. 1, and is not described here again.
As can be seen from fig. 3, compared with the embodiment corresponding to fig. 1, the flow 300 of the method for processing information in the present embodiment highlights the steps of performing echo cancellation and noise reduction on the audio collected by the vehicle-mounted audio collecting device. Therefore, the scheme described in this embodiment can generate the processed audio after echo cancellation and noise reduction, so that the audio acquired by the vehicle-mounted terminal application does not include acoustic echo and noise, which is more beneficial to the subsequent processing of the vehicle-mounted terminal application.
With further reference to fig. 4, as an implementation of the methods shown in the above figures, the present disclosure provides an embodiment of an apparatus for processing information, which corresponds to the method embodiment shown in fig. 1, and which is particularly applicable in various electronic devices.
